A composition for preparing an organic insulator, the composition comprising (i) at least one organic-inorganic hybrid material; (ii) at least one organometallic compound and/or organic polymer; and (iii) at least one solvent for dissolving the above two components, so that an organic insulator using the same has a low threshold voltage and driving voltage, and high charge carrier mobility and I/Iratio, thereby enhancing insulator characteristics. Further, the preparation of organic insulating film can be carried out by wet process, so that simplification of the process and cut of cost are achieved.

Composition for preparing organic insulator

Disclosed herein is an organic thin film transistor comprising a substrate, a gate electrode, an organic insulating layer, an organic active layer and source/drain electrodes, wherein the interface between the organic insulating layer and the organic active layer is of relief structure. According to the present invention, an organic thin film transistor of enhanced electric properties can be obtained regardless of the organic insulating materials used.

Organic thin film transistor enhanced in charge carrier mobility by virtue of surface relief structure
